Identity Shift in Computer-Mediated Environments

The present study uses a public commitment framework to examine how computer-mediated self-presentations can alter identities. Participants were asked to present with one of two traits, extroversion or introversion, in public or private computer-mediated communication. Public presentations were online, whereas private presentations took place in a text document. Only participants that presented themselves publicly internalized the trait presentation, suggesting that identity shift took place. Public self-presentations also contained more certain and definite forms of language than private self-presentations, suggesting that audiences evoke a more committed form of self-presentation. The findings in this research have important implications for the self-construction of identity online, particularly for individuals that use the Internet as a tool for public self-presentation, such as dating sites, social network sites, or blogs. Also, the findings highlight opportunities for theoretical development on identity construction as a function of computer-mediated communication.     

Displays that facilitate performance of multifrequency ratios during motor-respiratory coordination

A large number of ratios between movement and breathing are possible, but only a small number have been performed during exercise. The purpose of this study was twofold: (1) to investigate displays that might facilitate the performance of other ratios; and (2) to test predictions from the sine circle map and continued fractions in a model motor-respiratory task in which participants coordinated arm movement and breathing. Displays consisted of either real-time feedback or a template (non-feedback). The accuracy of ratio performance was significantly greater with the template in which the number and relative positioning of movements and breaths was depicted, compared to with real-time feedback. Across displays, the stability of ratio performance conformed to principles of the sine circle map and was significantly greater for ratios with longer continued fractions. Therefore, the motor-respiratory repertoire can be expanded by increasing participants’ understanding of the pattern to be performed, but performance is constrained by general dynamical principles.     

Detecting smugglers: Identifying strategies and behaviours in individuals in possession of illicit objects

Behaviour detection officers' task is to spot potential criminals in public spaces, but scientific research concerning what to look for is scarce. In two experiments, 52 (Experiment 1A) and 60 (Experiment 2A) participants carried out a mission involving a ferry crossing. Half were asked to smuggle an object; the other half were non-smugglers. In Experiment 2A, two confederates appeared to approach as if looking for someone on the ferry. Smugglers, more than non-smugglers, reported afterwards to have felt nervous, self-conscious, and conspicuous and to attempt behavioural control during the ferry crossing. The secretly videotaped ferry crossings were shown to 104 (Experiment 1B) and 120 (Experiment 2B) observers, tasked to identify the smugglers. Although they reported paying attention mostly to signs of nervousness, lie detection accuracy rate was poor (48% in Experiment 1 and 39.2% in Experiment 2) because their perceptions of nervousness did not match the experiences of nervousness reported by the (non)smugglers.     

Subjective well-being in urban adolescents of color

Relationships among predictors and criteria of subjective well-being were examined in a sample of 151 urban adolescents of color, ages 12-15. The relative strengths of family, peer, and school-related support and esteem in predicting three measures of subjective well-being (life satisfaction, positive affect, and negative affect) were explored. Results suggested that sense of worth in one's family explained a significant amount of variance in subjective well-being variables, above and beyond the contributions of individual, school, and peer-related variables. Implications for prevention and mental health promotion with urban adolescents of color are discussed based on these findings.     

VII—Rigidity and General Terms

In this paper I examine two ways of defining the rigidity of general terms. First I discuss the view that rigid general terms express essential properties. I argue that the view is ultimately unsatisfactory, although not on the basis of the standard objections raised against it. I then discuss the characterisation in terms of sameness of designation in every possible world. I defend that view from two objections but I argue that the approach, although basically right, should be interpreted cautiously.     

Articulatory behaviors of nonnative speakers: role of l2 proficiency and accent modification

To sound native-like, nonnative speakers need to approximate the articulatory patterns of native speakers. When nonnative speakers deviate from native speakers' production patterns, it gives rise to a nonnative accent. This study examines how proficiency in a second language (L2) is related to processing skills in L2, as measured by the accuracy of consonant production. 10 monolingual speakers of American English, 10 Bengali-English bilinguals with high proficiency in English, and 10 Bengali-English bilinguals with low proficiency in English participated. The participants spoke 16 nonwords of four different syllable lengths. Productions were phonetically transcribed. Results suggested that nonnative speakers' L2 proficiency differentially interacted with overall phonemic accuracy, usage of appropriate place, manner and voicing features, position of consonants within target words, and syllable length. Implications of these findings are discussed in light of customized strategies for modification of nonnative accents.     

Path analysis of exercise treatment-induced changes in psychological factors leading to weight loss

Physical activity may affect weight loss largely through psychological pathways associated with eating changes, especially in obese individuals whose caloric expenditure through exercise is typically small. Direct testing of this is, however, lacking. Previously sedentary adults (N?=?114; 77% female; M(age)?=?43.3 years), with a minimum body mass index (BMI) of 35 kg/m2 (M (BMI)?=?42.0 kg/m2), participated in a 24-week treatment of cognitive-behavioural exercise support and nutrition information. A path model based on tenets of social cognitive and self-efficacy theory was constructed. It was expected that improvements in self-efficacy, physical self-concept, body satisfaction and mood associated with the exercise treatment would predict changes in self-regulation and increased physical activity. It was also hypothesised that improvements in self-efficacy and self-regulation for appropriate eating would transfer from these relationships and predict weight loss. After three theoretically viable paths were added based on modification indices, structural equation modelling indicated a good fit with the data, χ2(16)?=?20.53, p?=?0.20; RMSEA?=?0.05; SRMR?=?0.06; CFI?=?0.97; TLI?=?0.95. Associations of psychological effects linked to exercise programme participation with predictors of appropriate eating and weight loss were found, and may inform theory, research and treatments.     

Latino/a Theology: Doing Theology Latinamente

Latino/a Theology is rising among theologians of Latin American descent in the United States. This article describes five characteristics: 1) it is specific to the cultural context of marginalized Hispanic history; 2) it focuses on the theme of mestizaje/mulatez, the biological and cultural mixing of European Spanish with Africans and indigenous Americans; 3) it derives from popular religion; 4) it deals with everyday life, lo cotidiano; 5) like liberation theology, it emphasizes praxis.     

The moderating effect of trivial triggering provocation on displaced aggression

Two studies examined the interaction between the presence or absence of (a) an initial provocation and (b) a subsequent minor triggering action on the part of the target of displaced aggression. Consistent with the triggering event being seen by participants as indeed trivial when administered by itself without prior provocation, exposure to it literally had no impact on aggression toward its source. When previously provoked, however, this subsequent triggering event strongly increased displaced aggression, causing it to reliably exceed both that displayed when there was no antecedent provocation and that elicited by provocation alone. Mediation analyses showed that for participants who had been provoked, subjective feelings of displeasure concerning the triggering event mediated the effect of the trigger on aggression.
